The Fate of the First Stars

The video explores the enigmatic Population III stars, the first stars formed after the Big Bang. These stars, devoid of heavy elements, played a crucial role in shaping the universe by enriching it with heavy elements and black holes. The video explains the classification of stars into three populations based on metallicity and discusses the challenges in finding Population III stars. It delves into the physics of star formation, the impact of metallicity, and the lifecycle of massive stars. The influence of Population III stars on the universe's evolution, including the formation of supermassive black holes and quasars, is also highlighted.
